The hindwings are ochreous- whitish with a grey posterior line.

With luck
About 10% of wildlife watchers report a Garden Pebble sighting in Liverpool on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 411th most-seen of the 632 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Garden Pebble in Liverpool on a given day, against under 5% in October to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Garden Pebble is recorded against all the insects logged in Liverpool (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
